First let's subtract 11 from both sides 11-k%2F2-11=60-11, which simplifies to -k%2F2=49. Now let's multiply both sides by -2: -k%2F2%2A%28-2%29=49%2A%28-2%29 which simplifies to k=-98. To check our answer, we substitute it into our original equation thusly: 11-%28-98%29%2F2=60. We simplify that to 11-%28-49%29=60 and even further to 11%2B49=60. We finally get 60=60, which is a true statement, and that means our answer of k=-98 is valid.
